HENRY V. WAGONER, OF BROOKLYN, NEW YORK.

BINDER.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed November 2], 1906. Serial No. 344,358.

To all rwhom it may concern:

Be it known that I, HENRY V. WAGONER, a citizen of the United States,residing at Bensonhurst, in the borough of Brooklyn and State of NewYork, have invented certain new and useful Improvements in Binders, ofwhich the following is a specification.

My invention relates to devices for holding loose leaves or sheets ofpaper or other material under clamp pressure, and either with, orwithout a cover. It is also adapted for holding magazines, note booksand pamphlets, as a book binding. Normally, the clamp employed standsopen, and is closed by a short lever, or by a key, and is held closed byan automatic catch until purposely released.

-The accompanying drawing illustrates the device, in which, Figure lpresents a planview with an open cover thereon and the clamp inoperative position. The cover, leaves and base-board, are shownfragmentarily. Fig. 2 is a plan ofthe upper end of a loose sheet ofpaper. Fig. 3 is an enlarged side view of Fig. l, but with the clampopen and the cover turned over against the under side of the base-board.Fig. 4 is a rear elevation of the catch, enlarged. Fig. 5 is a detailview of an upper corner of the sheet support, and Fig. 6 is a plan ofthe middle part of the device showing a modification of the clamp.

Like letters of reference denote corresponding parts in the severalviews.

The letter A designates the base-board on which the sheets or leaves aare laid.

B, B are supports for a rock-shaft O, and are secured to the base A,near one of its sides or ends. These supports are preferably formed ofmetal plates, secured to the base A, and having their ends b, b, turnedup at a right angle to form the bearings.

B B are extensions of the plates B, and upon these are erected the sheetretainers b, b, which engage lateral notches a/, a', in said sheets.They also engage the notches j, j, in the sheet support J, whichisplaced beneath one or more of the sheets to insure a smooth and firmwriting surface.

The shaft C is rocked by a short lever or handle c, attached to it nearone of its ends. When this lever is depressed, it is engaged by anautomatic spring catch secured on the extension B of the plate B. Thisshaft may also be rocked by a key t', adapted to fit upon the angularend c of the shaft C. in which case a short arm c on the shaft isengaged by the catch.

Coil springs E, E are provided on the rock-shaft, each having an end ebent to engage a hole in the shaft; or being attached to the shaft inany other preferred way. The other ends of the springs E are secured tothe clamp piece I. This clamp piece may be formed in any preferred way,but I here show it to be substantially flat with a corrugation k uponit. The clamp I stands open normally, and when the lever c is depressedan `part b to form the finger pressure piece f/ elastic pressure issecured upon the leaves a; said pressure being maintained by the catchuntil purposely released. i This catch is composed of supports d, d, onthe extension B, a rod d on said supports, a coil spring d on said rodand having one end anchored and its other end bearing against a detentF, whose upper curved part f is adapted to engage the depressed leverarm c,

and whose lower end extends outwardly through the G is the cover of thedevice whose edge g is attached to the hinges H, II, whose ends are bentto engage holes t'/ in the part b. This' construction permits the coverto be turned over backwards against the under side of the base A.

.I is a leaf support to be placed under one or more of the leaves a,when writing thereon, to give them a smooth and firm surface. It hasnotches j, j, to engage the retainers b.

In the modification shown in Fig. G the clamp consists of a continuationc/ of the wire E. This part e/ is placed between the leaves of amagazine or note book m, and holds it securely when the clamp is underpressure.

I do not limit myself to the exact construction of this device as shown,since more or less than two springs E might be used: also the base Amight be formed of metal and the supports B be formed integral with it.And so in other parts of the device, in which I reserve the right tomake equivalent changes- What I claim and desire to secure, is,-

1. A binder comprising a base, a rock-shaft, means on said base forcarrying said rock-shaft, a pressure clamp, springs coiled about saidrock-shaft, one end of said springs beingrattached to said rock-shaftand the other ends of the springs b'eing attached to the pressure clamp,means for actuating said rock-shaft thus tightening said spring coilsand producing pressure en the clamp, and means for retaining andreleasing the pressure so produced.

2. A hinder comprising a base, shaft bearings on said hase, a 1'ockshaftin said bearings, coil springs attached to said shaft, a clamp attachedto said springs, means to actuate said shaft to produce pressure by saidclamp and means to maintain, and to release, said pressure, asdescribed.

3. A binder comprising` a base, sheet retainers on said base, sheetshaving notches engaged by said retainers, shaft bearings on said base, arock-shaft in said bearings, a short arm on said rock-shaft, coilsprings on said shaft one of whose ends engages said shaft, a corrugatedpressure clamp attached to the other ends of said springs, said clampstanding open normally, a key to close said clamp, a catch to engagesaid arm on said shaft, and a sheet support provided with notches toengage said sheet retainers as herein set forth.

4. A catch comprising supports on a base, a rod on said supports, a coilspring on said rod, a detent loose on said rod having its upper partadapted for engagement and its lower part extended to form a pressurepiece, said detent being under pressure of said coil spring asdescribed.

5. In a binder a base having supports for a clamping device, holes insaid supports, a cover for said hinder, a

Wire hinge attached to said cover and having its ends bent to rotate insaid holes ln said supports as described.`

G. ln a leaf binder comprising a base, a shaft support thereonalrockshaft in said support, a clamp, spring connection between saidi'ocl-sl1aft and clamp, a lever to actuate said shaft, a Spring' catchto engage said lever when depressed means to release said lever, andmeans to retain said leaves on the base board, as described.

'i'. A binder comprising a base, shaft bearings on said buse, arock-shaft in said bearings, coil springs on Said shaft, one of whoseends engages said shaft, a pressure clamp attached to the other ends ofsaid springs, said pressure clamp standing open normally, means toactuate said rock-shaft to produce a tension on said clamp, and means toretain the tension so obtained, until purposely released.

8. A catch comprising a rocking detent freely journaled on a bearingrod, a spring, holding said detent in operative position, and aprojection on said detent by which it is forced out of operativeposition, as described.

ln testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
